1.I picked up the rake and began to sweep the oak leaves over the edge of the roof, watching them whump to the ground.
我拿起耙子开始把橡树叶子扫到屋顶的边上，看着叶子噗噗地往地上落。
2.My mouth dry, I flew closer, expecting the zing of bullets and the whump of heavy weapons fire.
我口很干，飞得更低了，期盼着子弹呼啸和重武器开火的嗡嗡声。
3.As his car passed, no child darted out, but a brick sailed out and --WHUMP!
在他的车子开过去时，没有孩子奔跑出来，但有一个砖块飞了出来——嘭！
